Don'tBeAfraid, I don't know about Tea Tree Oil in the ears, but when we were kids, my mom always put warmed Sweet Oil in our ears when we had earaches. I don't know if it actually healed anything, but it DID make the pain ease quite a bit.

That's certainly true, and a common thing people do in my region. You actually used to be able to buy "sweet oil" in drugstores.
